摘要： A communication system that transfers digital data on a fixed frequency channel of a radio frequency band in the presence of interference from at least one FHSS interference source includes a time diversity generation circuit. The time diversity circuit compacts a duration of data frames then replicate the time compressed data frames. The duplicated time compressed frames of data are transmitted to a communication receiver that has a time diversity data recovery circuit. The time diversity data recovery circuit buffers the received compressed and replicated data frames, evaluates whether each of the duplicated time compressed data frames are received correctly. If any one of the duplicated time compressed data frames is destroyed, the copy of the destroyed duplicated time compressed data frame is used to recover the data frame.

摘要： A serially linked digital data content relaying system that wirelessly transfers digital data content files such digital audio files, digital video files, or digital voice paging files includes a virtual serial network. The virtual serial network includes a master controller node device and multiple reproduction node devices. The master controller node device maintains digital data content files for distribution through the virtual serial network of the digital data content relaying system to the reproduction node devices. Each reproduction node device is serially in wireless communication two reproduction node devices that are in close proximity. A first reproduction node device of the plurality of reproduction node devices is in wireless communication with the master controller server to receive the digital data content files as radio frequency signals.

摘要： A wireless network system includes a wireless master control hub in communication with a personal computer and provides a control protocol to human interface devices for communication to request and receive command messages, control messages, and data from the personal computer. Slave human interface devices controllers are associated with one of the human interface devices to provide translation of command or data information from the associated human interface device to the wireless control hub. The wireless control hub generates a synchronization signal to allow any of the human interface devices to permit communication between each of the human interface devices and the wireless control hub. The wireless control hub generates a receiving and transmitting time slot assignment signal for each of the human interface devices for a communication frame for communicating file requests and data between the personal computer and the human interface devices.
